Competitive Domain Analysis

[tinyfactory]

In the competitve domian analysis my domain root (gpscity.com) is showing up as a 404 not found.  My competition is showing up as 200.  My site is live, index and viewable, but I'm wondering if this has an effect on my rankings?  What can I do to test that it's not returning a 404 when the crawlers view my site?

Try making it www.gpscity.com. Your sans www URL redirects to the www version, so include the www and see if that helps.
